Idle No More is a grassroots movement aimed at protecting native treaty rights and improving native living conditions in general. It was created in response to the Harper Conservatives' introduction of Bill C-45, an omnibus bill which many native activists claim weaken environmental protection laws, particularly those regarding protected waterways. Since four activists came up with the Idle No More Twitter hashtag in November 2012, the movement has grown to include several actions nationwide.

The ongoing hunger strike of Attiwapiskat Chief Theresa Spence continues to serve as a catalyst for the movement.
